EAST RUTHERFORD, N.J. (CBSNewYork/AP) - The developer of a New Jersey megamall project is countersuing the New York Giants and the New York Jets.

Developer Triple Five says the NFL teams are engaging in a “campaign to delay, thwart and ultimately prevent” the American Dream project from being built at the Meadowlands sports complex. The company says the teams are preventing it from getting permits to build on the land.

The teams say the mall expansion would create a traffic nightmare, but the developer says studies indicate no such thing would happen.

Marcus said Triple Five also wants the teams to pay for damages “which they have caused us through delay.”

Triple Five says the teams are trying to keep a monopoly on the land and revenue around the sports complex.

The teams say they’re “disappointed” and plan to “vigorously pursue” their court action.

“We think it’s unfortunate,” said Karen Kessler, a spokesperson for both football teams, adding that this latest action “basically flies in the face of the court’s express prior ruling that said that the court would decide this breach of contract case.”

Putney reported Triple Five still plans to go ahead with groundbreaking for the expansion next month.
